Ill buy it at that price!
Runs OK on 30 and 17M as is, needs a few plate choke turns removed for
12M.
If you keep it loaded heavily and output at 1200W it should last a long
time. Do the usual bit when bringing up the HV for the first time.

Has 3 8874's.
Is it QSK?
No
Will it do the WARC bands as is?
No, needs a different RFC if you want 17M. Nice amp with the basic PS
xfmr, the CA model has the Hypersil one.
>Price somewhere between $699 and $999 best guess.
I know someone who would buy it in most any condx. He already has new
3CX800's if the 8874's are bad.

Smokes bandswitches, splatters when driven hard, no bargain at $699.
